Analyzing differences amoung Copolymer Acetal and Homopolymer Acetal in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is easy to turn, however it requires reduced speeds. I have used this plastic to make Scottish small pipes chanters. I have bought many items from Industrial Plastic. The small parts always ship quickly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, and they have similar physical properties. They appear the same, but for practical use there are a few differences that may make one preferable than the other. It also depends on your application. As with all plastic materials, be sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,as it gives an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is certainly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the automotive industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in moisture applications. This environment suits acetal well because the low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
